Our server has 6 CPUs. using this command : /usr/bin/top -b -n1

I got this result :

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
14841 root      25   0 5503m 3.5g  18m S 191.2 59.8  20:32.52 java              
  929 root      10  -5     0    0    0 S  1.9  0.0   0:51.12 kjournald      

Why is the CPU could be more that 100% (191.2%)? Is it because, the server has more than 1 CPU?

Please help. Thanks

    Thanks, if pressing "1" we could see each CPU. The info is really useful for.

    But my question is not answered by that info.

    So what does it mean by "191.2%" ?

    You might install and run 'htop'.  It give a graphic representation of cpu usage, as well as the info provided by top.
